CROSS-REFERENCE TO RELATED APPLICATION

The present application is a non-provisional of, and claims priority to, U.S. Patent Application No. 63/120,774 filed Dec. 3, 2020, which is incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

The present disclosure generally relates to shingle removal, and more particularly to shingle removal using a motorized shingle remover.

BACKGROUND

Shingle removal has always involved manual labor. Workers used blades with handles to chop and cut the shingles to remove them from a roof. These chopped shingles are then pushed or shoveled off of the roof to a dumpster on the ground below. This method can take a long time and takes a lot of physical labor. Despite the time and labor required, it also often does not get all of the roofing nails, used for the old shingles, out of the roof. Removing these nails requires either cutting them off at the roof or having a worker go and remove them one by one. This is an incredibly slow and arduous process for removing shingles before the work of installing new shingles can even begin.

DETAILED DESCRIPTION

Embodiments of the present disclosure may generally provide for a motorized shingle remover that may include a motor, a plurality of cutting blades, a plurality of wheels, a vacuum, a scrapping blade, and a handle. The motorized shingle remover may provide a more efficient method of removing shingles and nails from a roof.

FIG. 1 depicts a motorized shingle remover according to an embodiment of the present disclosure. Shingle remover 10 may have body 101 and handle 107. Body 101 may be made of many different materials including, but not limited to, wood, aluminum, or steel. Handle 107 may be designed to allow the user to maneuver shingle remover 10 around the roof to fully remove shingles and nails. Shingle remover 10 also may include braking mechanism 108. In an embodiment of the present disclosure, braking mechanism 108 may be connected to handle 107. As handle 107 is pulled back, braking mechanism 108 may be released. Body 101 may be maneuverable through a plurality of wheels 105. The plurality of wheels 105 may be able to move in all directions to facilitate removal of shingles in an embodiment of the present disclosure; however, there may be embodiments of the present disclosure where the plurality of wheels 105 are not adjustable. Body 101 may also feature a plurality of cutting blades 103. The plurality of cutting blades 103 may help perform the work to remove the shingles and nails. More specifically, the plurality of cutting blades 103 may be attached to a shaft that spins the plurality of cutting blades 103 to scrape materials off of the roof and pull them away from the surface.

FIG. 2 depicts another view of the motorized shingle remover of FIG. 1 according to an embodiment of the present disclosure. Shingle remover 10 is made up of body 101 and handle 107. Body 101 may be able to be moved around the roof surface using a plurality of wheels 105. Wheels 105 may be able to be moved in all directions to facilitate shingle removal; however, there may be embodiments of the present disclosure where the plurality of wheels 105 are not adjustable. Actual removal of shingles may be performed by a plurality of cutting blades 103. The plurality of cutting blades 103 may be attached to a shaft that may be adjustable and may spin around to cut shingles, thereby pulling the shingles and nails up into body 101. As the debris is being pulled into body 101, scrapper 201 may pull the debris away from the plurality of cutting blades 103. Once scrapper 201 has pulled the debris off the plurality of cutting blades 103, the contents may be disposed of by being pulled out of body 101 using vacuum 203. Vacuum 203 may include a hose made of a durable material so that it is not ripped or pierced by shingle debris or nails being pulled from body 101. However, there may be embodiments of the present disclosure where the vacuum system may be replaced by inclusion of an air nozzle in front of each wheel to blow dust/debris away (FIG. 3B). Accordingly, the wheels, which may be formed of soft rubber in an embodiment of the present disclosure, may better maintain traction on the roof during use.

It also should be appreciated that a soft rubber track may be used in place of the plurality of wheels in an embodiment of the present disclosure. It may be further appreciated that a deflector may be incorporated in the front portion of body 101 in some embodiments of the present disclosure.

FIG. 3A depicts the underside of the motorized shingle remover of FIG. 1 according to an embodiment of the present disclosure. More specifically, FIG. 3A depicts the relative placement of the plurality of wheels 105 and the plurality of cutting blades 103 on the underside of body 101. The plurality of cutting blades 103 may be attached to shaft 303 by bolts 301 or other similar fastening mechanism. The plurality of cutting blades 103 may have an angle to them that may aid in cutting as well as in pulling the cut debris away from the roof for disposal. The angle of the plurality of cutting blades 103 may allow the plurality of cutting blades 103 to not just scrape the surface of the roof but may allow the blades to reach under the shingles and run up against the surface of the roof. The angle of the plurality of cutting blades 103 in running up against the surface of the roof may allow the plurality of cutting blades 103 to get up under the head of the nails and may allow the blades to pull the nails up and out of the roof. If the plurality of blades 103 were straight, they would simply slowly scrape away the shingles and not be able to address the remaining nails.

FIGS. 4 and 5 depict a motor for the motorized shingle remover of FIG. 1 according to an embodiment of the present disclosure. The present embodiment shows motor 401 on top of body 101; however, it should be appreciated that body 101 may be designed to cover motor 401 without departing from the present disclosure. Shaft 303 may run through body 101 and may be adjustable in an up and down direction for height in an embodiment of the present disclosure. Shaft 303 may also have pulley 403 attached to one end that may extend from body 101. Motor 401 and pulley 403 may be attached with belt 405 in an embodiment of the present disclosure. As motor 401 runs, motor shaft 407 rotates. The rotation of motor shaft 407 may pull belt 405, which may then transfer this rotational energy down to pulley 403. The turning of pulley 403 may in turn rotate shaft 303 which may allow the motorized shingle remover to function. It should be appreciated that motors of different sizes and strengths may be used without departing from the current disclosure. The integration of motor 401 into the shingle remover may allow removal to go much quicker and require less manual labor.

FIG. 6 depicts a front facing view of the motorized shingle remover of FIG. 1 according to an embodiment of the present disclosure. Shingle remover 10 is shown on a sample roof. Motor 401 may be positioned on top of body 101 in an embodiment of the present disclosure. Motor 401 may be connected to a plurality of cutting blades 103 through belt 405 that may allow the plurality of cutting blades 103 to turn and cut and remove the shingles. The wheels on body 101 may allow shingle remover 10 to move in any direction based on the angle of the roof and the direction the shingles are laying. FIG. 6 shows how shingle remover 10 may cut the shingles to remove them from the roof. The chopped-up shingles seen closest to shingle remover 10 have had portions chopped and ripped away. FIG. 7 depicts a side view of a motorized shingle remover according to another embodiment of the present disclosure.
